Universal Tip

Tip (or its full name, Universal Tip) is a programmable tooltip that can be used with any Mac OS app. You can select the text and hit the shortcuts to activate the tooltip with useful info.

"Useful info" is programmed by YOU using your fav programming language.

For me, who is prone to Repetitive Strain Injury (RSI), Tip reduces hand movement and the risk of the injury. It also makes me work faster. I encourage you to try Tip today!

Installation

Install Tip from Mac App Store
- You can also download it from the release page and move Tip,app to under /Applications
Download and copy scripts/provider.script to ~/Library/Application\ Scripts/tanin.tip/provider.script. Run chmod 755 ~/Library/Application\ Scripts/tanin.tip/provider.script.
- Or you can simply run: curl -o ~/Library/Application\ Scripts/tanin.tip/ --create-dirs https://raw.githubusercontent.com/tanin47/tip/master/scripts/provider.script && chmod 755 ~/Library/Application\ Scripts/tanin.tip/provider.script
Go to System Preferences > Keyboard > Shortcuts > Services > Scroll down to the "Text" section. You should see "Tip: open tips" under the "Text" section.
- Please make sure to check it.
- You can also set the shortcuts here.

The sample provider script is in Ruby, so you need Ruby to run it. Otherwise, you can make your own provider as well.

See how to develop the provider here.

Privacy

Tip runs in App Sandbox, which protects users by limiting the privileges of the app to its intended functionality. App Sandbox gives our users peace of mind.

With App Sandbox, Tip can only read/write files from a few predefined directories and, specifically, can only execute (not write) files within ~/Library/Application\ Scripts/tanin.tip.

This is the reason why the provider script is under ~/Library/Application\ Scripts/tanin.tip/.

As a reminder, please always review a downloaded provider script before using it.

Usage

Select the text
Hit the configured short key. The default shortcut is Cmd + &.
The tooltip with relevant info will show
Use arrow keys to choose an item in the tooltip and hit 'Enter' to perform the appropriate action. Alternatively, you can click an item as well

Currently, Tip supports 2 actions: (1) Copy to clipboard if the item is text, and (2) Open URL if the item is URL.

Customize the shortcut

Go to System Preferences > Keyboard > Shortcuts > Services and set the shortcut for "Tip: open tips".

If your shortcut doesn't include the Command key, you will need to activate it manually by:

Selecting a text
Clicking on the application menu > Services > "Tip: open tips"

Now you'll be able to use the new shortcut for Tip.

Technical detail

Tip is a system-wide service on Mac. When user selects text and hits the shortcut, the selected text is sent to Tip. Then, Tip invokes the command-line tool with the selected text as the first argument, i.e ~/Library/Application\ Scripts/tanin.tip/provider.script [selected-text].

The command-line tool processes the input, decides which info to show, and prints the tip items as JSON that looks like below:

[
  {"type": "text", "value": "Some text"},
  {"type": "url", "label": "Go to JIRA", "value": "https://your-jira-url/JIRA-0001"},
]

Tip processes the JSON and renders the tooltip at the mouse location.

FAQ
